The Great King Guthrum, Aethelstan of East Anglia. Viking Sagas, #22

Born into the shifting rivalries of ninth century Denmark, Guthrum grows up in a world where bloodlines are both protection and peril. Nephew to a fragile royal house and shaped by dynastic instability, he learns early that survival demands more than strength. It demands patience, intelligence, and the courage to change. From his first practice battles beside Halfdan, son of Ragnar, to the long, brutal campaigns of the Great Heathen Army, Guthrum rises through loyalty, strategy, and quiet resolve.
He fights across England, stands in the shield wall against Wessex, and launches the daring Epiphany attack on Alfred the Great's court at Chippenham. The Great King Guthrum, Æthelstan of East Anglia is a sweeping, historically grounded adventure that traces one man's journey from Viking war leader to architect of the Danelaw. It is a story of ambition, friendship, defeat, negotiation, and legacy, showing how the Viking Age in England did not end in annihilation, but in uneasy coexistence.
This and every book in the series includes a detailed historical time to help separate legend from documented history and dispel enduring myth.
